FROM THE CHAIR Dear Alumni, Colleagues, and Friends, Greetings from the School of Materials Science and Engineering at Georgia Tech! The inherently interdisciplinary nature of Materials Science and Engineering and its breadth spanning the scientific theories of material behavior to engineering challenges imposed on material performance, make it a fascinating major. It is a major for those aspiring to make Noble Prize-winning discoveries as well as those aiming to be entrepreneurs and tackle societal problems through their innovations. In our position as faculty, we have the responsibility to educate the next generation of materials science and engineering leaders by immersing them in the fundamentals and actively engaging them in independent and experiential learning beyond the classroom. It is also our responsibility to lead the way with innovative research that solves intractable problems and creates new paths of investigation for others to follow. This requires setting a new standard for infrastructure and building an environment that nurtures the culture of creativity, curiosity, inclusiveness, and service to society. It is indeed most humbling to be in this position. I hope you will enjoy reading the stories of our people as we stride forward. The MSE “make and measure space,� the MILL - Materials Innovation and Learning Laboratory - continues to serve several hundred students from more than 20 schools across Georgia Tech. It is a peer-to-peer learning space that is empowering student learning and inspiring creativity through hands-on discovery, design, and characterization of materials. It is promoting the culture of team work and lab safety - two attributes that are essential for training our future workforce. We are seeking funds for its expansion to a 6000 square foot openaccess contiguous space, that will serve to bring together the entire community of students. We welcomed to the School, Juan-Pablo Correa-Baena who joined us as an assistant professor in January 2019. His research focuses on the understanding and control of electronic dynamics at the nanoscale for low-cost semiconductors, including halide perovskites for solar cell and light emitting diode applications. Alena Alamgir and Himani Sharma also joined MSE this fall; Alena serves as the Director for Technical Communication, responsible for instruction of technical communication skills for both undergraduate and graduate students, and Himani takes over the teaching of our two core undergraduate laboratory courses at the junior and senior levels. We are delighted with the establishment of the Novelis Innovation Hub. Novelis Inc., with their global R&D headquarters located in northwest Atlanta, has committed to providing a minimum of $2.5 million to promote applied and basic sponsored research, and philanthropic support for faculty/student fellowships.

The processing team has expanded and moved in the hub in Love 176. The team has also diversified their 3D printer line-up with Prusa and Ultimaker units and added a sewing machine, an embroidery station, and a vinyl cutter. The measurement team has added a differential scanning calorimetry. In the Learning and Discovery (L&D) division, the Recycling Innovation Team was created at the beginning of the fall semester to research how to develop processes to reliably recycle the MILL’s 3D-printed PLA parts into new PLA filament. The Cold Sintering Team won the MSE poster competition award last spring, and the High Entropy Alloys Team has been hard at work experimenting with 3D printing and sintering metal alloys. In October, the MILL started offering workshops to the GT community through their Science of Art L&D Team. It has held 11 events to promote materials science and engineering among other Schools and to teach artists how they can take advantage of material properties to create art. The MILL specializes in glass fusing events, and in collaboration with the ECE Hive Makerspace, it has recently expanded its selection of materials to include stained glass. When not managing events, the Science of Art Team works on experimental materials art research in epoxy and glass fabrication, such as creating imprints of organic materials in glass.

Faisal Alamgir Fundamental Mechanisms Behind Functioning of Active Materials What excites Faisal Alamgir most in his research is the prospect of figuring out the fundamental limits on how materials work and then, if possible, conspiring to emancipate them from their constraints. Detailed knowledge gained from the former allows him to design materials to realize the latter. Both of these research paths have already been successfully explored by his lab projects on materials for energy storage, conversion, and capture. Elucidation of how energy-materials work: To determine in fine detail how materials work, the Alamgir lab uses element-specific x-ray techniques to reveal atomic-level structure (under real-world conditions whenever possible). Using these methods, the role of each element can be determined and detailed roadmaps can be produced. The members of the Alamgir lab have demonstrated this approach on Li-ion batteries, as well as on polymer electrolyte membrane and solid oxide fuel cells (PEMFC and SOFC). Pushing materials beyond their limits: Dr. Alamgir and his group have been the first to demonstrate a new paradigm for graphene-templated, epitaxial, dimensionally-tunable, atomically-thin catalyst system that is support-flexible in design. This epitaxial graphene-metal system is a platform that transcends the activitystability dilemma in catalysis since atomically-thin films render nearly every atom to a surface site while the bonds from the epitaxy also provide increased stability against catalyst deactivation. The platinum-graphene (Pt/GR) catalyst discovered by the Alamgir group exemplifies this effect by providing a “chemically transparent” barrier with “infinite” resistance to activity loss from Pt dissolution and agglomeration in 1000 cycles of the canonical oxygen reduction reaction. By inducing chemical bonding with graphene in the Pt/GR catalyst, the Alamgir lab has pushed the catalytic properties beyond that of a standard Pt catalyst, i.e. they have produced a supra-Pt catalyst. Core competency and philosophy: The research conducted in the Alamgir lab benefits from a unique combination of three synergistic capabilities; synthesis of near-surface architectures, measurement of atomic-level structure evolution under in situ conditions, and measurements towards prediction of electrochemical properties, all from the perspective of the local atomic structure. Taken together, they reflect Alamgir’s philosophy of always returning to the atomic scale to discover the origins of structure-property relationships in materials. Faisal Alamgir is an associate professor in the School of Materials Science and Engineering at the Georgia Institute of Technology. Research in Alamgir's group has focused on unraveling the fundamental mechanisms behind the functioning of active materials in (electro)catalysts, batteries and (photo)electrochemical devices. Often, synchrotron based (in/ex)-situ/operando methods are used to elicit underlying relationships between composition, electronic/atomic structure and material properties (e.g. electrical, optical, magnetic). In the materials space, Alamgir has been working on charge and strain transfer between/through 2D materials and metals/metal-oxides on layered-oxide based cathode materials for rechargeable batteries, development of poison tolerant electrodes for solid oxide fuel cells, and on transparent conductors and nanostructured semiconductors for solar cells. faisal.alamgir@mse.gatech.edu 12

Chris Muhlstein Understanding and Controlling Subcritical Crack Growth in Ultrathin Sheets Deformation and fracture of materials must be controlled to insure effective manufacturing and product performance. Many of the conventional characterization and design tools are ineffective when the material is in the form of a very thin sheet. When the sheets are flexible and can drape and sag under their own weight, engineering models must capture extreme aspect ratios (low thickness-to-width ratios), complex 3-dimensional effects (wrinkling, buckling, necking, etc.), and unique thickness-dependent properties. The Muhlstein Research Group is addressing this challenge by developing novel techniques to characterize and model the deformation, degradation, and failure of flexible forms of such materials. Their work is the state of the art in engineering of flexible substrates for applications such as disposable electronics, flexible displays, and even packaging applications.

Muhlstein leads an interdisciplinary group that uses techniques from electronics, computer science, materials & manufacturing, and optics. In their NSF-sponsored program, “Understanding and Controlling Subcritical Crack Growth in Large Freestanding Metallic Nanosheets (NSF DMR 1609817),” they found a crack growth mode that is unique to very thin forms of materials. The quasi-static steady-state crack growth under fully-plastic conditions was detected using their open-source, full-field strain mapping platform. They discovered previously unknown zones of active plasticity that remained the same as the crack grew. Permanent (plastic) strains spanned the width of the specimen when cracks grew under fully-plastic conditions (Figure 1a). The details of the crack growth mechanism were lost in the extensive damage that developed between the opposing cracks in the double edge notched tearing specimen. Data mining of the strain fields between the crack tips revealed stable, incremental zones of active plasticity that surrounded fracture process zones (Figure 1b). The fracture toughness (steady-state crack growth resistance) could be predicted from a characteristic stress that εyy εyy was a function of the specimen thickness. 9.1 9.1 These developments will change how we 7.8 7.8 engineer components 6.5 based on flexible forms 6.5 of materials.

Chris Muhlstein is an associate director of MPRL and associate professor in the School of Materials Science and Engineering at the Georgia Institute of Technology. His research group is focused on experimental studies of deformation, degradation, and failure of flexible forms of materials such as thin sheets and fibers. The research is driven by the engineering demand for flexible electronics, biomedical devices, and advanced structural materials. In most cases the materials are so thin and fragile that non-contact techniques must be used to measure the strains that develop during deformation. chris.muhlstein@mse.gatech.edu MSE.GATECH.EDU

Satish Kumar Carbon Fibers, Multifunctional Fibers, Nanocomposite Materials, and High Surface Area Carbon Through funding from a DARPA program, Satish Kumar has set up a unique fiber manufacturing facility, which includes spinning and continuous stabilization and carbonization lines in 4000 square feet of class 1000 clean room space at Georgia Tech. Kumar utilizes this facility to manufacture various types of fiber and their composites. High Strength and High Modulus Carbon Fibers. Using gel fiber spinning technology, novel carbon fibers have been manufactured reaching 30% higher modulus over the state-of-the art carbon fiber (e.g., IM7) without compromising tensile strength. Composites taking advantage of these fiber properties, are expected to further reduce the weight of airplane parts (e.g., in Boeing 787) by additional 15%. Polyacrylonitrile (PAN) /carbon nanotube (CNT) nanocomposites. Nanocomposites fibers made using PAN/CNT show that carbonized PAN is templated on the CNT surface, and that even a small amount of CNT (<1 wt%) significantly affects their thermal and electrical conductivity. Consequently, Joule heating can be used to increase the fiber temperature by up to several hundred degrees Celsius, even approaching 1,000°C. Likewise, other polymer/CNT fibers can be developed for heating applications, including heated textiles. Carbon nanotubes change the properties of polymers, including the ability to tailor electrical conductivity over 16 orders of magnitude, thermal conductivity, thermo mechanical properties, microwave absorption capability, etc. Polymer crystallization, orientation, and rheological behavior is also significantly affected using CNTs. Fiber spinning system at Georgia Tech
Nanocomposite fibers with multiple functionalities. Hollow Carbon Fibers with honey-comb structure have been fabricated having a density of 1.2 g/cm3; by comparison, the density of the state-of-the-art solid carbon fiber is 1.76 g/cm3. Similar to CNTs, carbonized PAN can also be templated on BNNTs to provide additional functionality to carbon fibers. Fibers from iron oxide nanoparticles containing PAN have been shown to exhibit super paramagnetic behavior. By using a novel bi-component fiber spinning approach, Kumar’s group has been able to manufacture carbon fibers with an effective diameter as small as 1-2 µm, while the current stateof-the-art carbon fibers have a diameter of ~5 µm. PAN-based carbon fibers incorporating renewable bio-content such as cellulose nanocrystals (CNC) and lignin, and bi-component fibers with sheath-core, islands-in-a-sea, and other crosssectional geometries have been fabricated. Fibers with many Hollow carbon fibers manufactured at Georgia Tech other functionalities can also be fabricated. 14

High surface area carbon. Kumar’s group has invented a process to economically manufacture largescale quantities of high surface area carbon (3000 to 3500 m2/g) from polyacrylonitrile (PAN) copolymer for applications such as supercapacitor electrodes (with more than two times energy density than the current stateof-the-art), electrode material for hybrid Li-ion battery, catalysis support, and for capacitive water desalination. Biomedical Applications. Kumar’s group is also interested in developing biomedical applications of fibers, nanofibers, and nanocomposite materials. They have collaborated with Biomedical Engineering faculty at Georgia Tech to fabricate polymeric nanofiber scaffolds, which have been found to be effective in bridging long peripheral nerve gap. The group has also collaborated with Augusta University on dental materials research to help prevent effects of gum disease. Interphase tailoring. Kumar’s research has shown that large changes in properties can be achieved with appropriately tailored interphase. For example, 150% increase in impact strength of polypropylene has been achieved by using only 1 wt% CNT, with previous best increase in impact strength being ~20%. In another development, Kumar’s research has shown that PMMA forms an ordered helical wrap around single wall carbon nanotubes (SWCNT), creating very stable dispersions in select organic solvents. Nanocomposites using thermosetting resins. Under NASA’s Space Technology Research Institute on composite materials, Kumar’s group is fabricating nanocomposites using thermosetting materials (e.g., BMI and epoxy resins), and CNTs.

Natalie Stingelin Cool Plastics for a Greener World With seabirds trapped in six-pack plastic rings and islands of indestructible garbage accumulating mid-ocean, the idea that plastics could significantly contribute to a sustainable future might seem far-fetched. However, new smart photonic and electronic plastics may yet rescue the reputation of this ubiquitous 20th-century material. The use of such functional plastics in car manufacturing and building construction could improve energy efficiency and drastically reduce the need for air conditioning. Various members of the Stingelin group work on designing plastics whose photonic and electronic functions could be used to make more sustainable technologies. One line of inquiry that we are pursuing concerns the question whether the new polymer-based systems can offer the same flexibility, softness, and light weight as commodity plastics, such as polyethylene, polypropylene, polyesters and polyamides (Nylons®), while also controling the flow of light (i.e. photons). Such a function could enhance the energy (light) harvesting capability of, e.g., photovoltaic devices by reducing unwanted light reflections at critical device interfaces. These systems can also be used to aid light out-coupling from light-emitting diodes, increasing their brightness while keeping their energy consumption the same. Other potential uses for such systems include photonic heat mirrors that can prevent heat from building up in solar cells while they are in use, which would, in turn, reduce their performance degradation. Moreover, such mirrors can be used to reduce the energy we currently expend to keep buildings at the temperature we want, or to provide new alternatives for dynamic greenhouse technology platforms, which can manage light for optimal plant growth, harvest excess light energy for power generation to be used in the greenhouse, and provide thermal management to reduce energy use and control pests. Figure 1. Inorganic/organic hybrid materials developed in the Stingelin group allow to produce a large variety of photonic structures. A. Simplified schematic of the hybrid materials produced with commodity plastics such as poly(vinyl alcohol) that allow to produce multilayer structures using lowrefractive index component fluorinated polymers or commodity plastics such as PMMA (Plexiglas®). B. Picture of a glass tube that was partly coated with an antireflection coating based on such high-refractive index hybrids/low refractive index multilayers. C. Using slightly different multilayer structures based on socalled distributed Bragg reflectors, mirrors can be produced by simple solution-processing. The reflection/ transmission of those mirrors can be tuned by the selection of the refractive index of the materials used and layer thicknesses.
